Abstract:
Embodiments are provided that include a method for fabricating a multi-die package including: placing a plurality of flip chip dies and splitter dies on the sacrificial carrier; performing solder reflow to join solder bumps of each flip chip die and each splitter die to the sacrificial carrier that includes test probe circuitry; testing the flip chip and splitter dies; replacing any faulty dies; overmolding the flip chip and splitter dies on the sacrificial carrier to form a panel of embedded dies; planarizing the panel of embedded dies to expose back surfaces of the embedded dies; forming a metallization layer across the back surface of the panel of embedded dies; and removing the sacrificial carrier to expose a front surface of the panel of embedded dies, wherein a contact surface of each solder bump of each flip chip die and splitter die is exposed in the front surface.
